A proven preventive solution, IronPort Virus Outbreak Filters provide a critical first layer of defense against outbreaks hours before signatures used by traditional anti-virus solutions are in place. Real world results show an average lead time over reactive anti-virus solutions of 14 hours, along with an extremely high catch rate and near zero misclassifications. Integrated into IronPort's C-Series email security appliances, IronPort Virus Outbreak Filters perform a threat assessment of inbound and outbound messages, and quarantines suspicious messages temporarily. Messages are automatically released once signatures from traditional anti-virus vendors are deployed.
